Methods

Constructors

A DateTime object that will be used to fill in missing information from incomplete date/time formats.

This key is optional.

cut_off_year

A integer representing the cut-off point between interpreting 2-digits years as 19xx or 20xx.

2-digit years < legacy_year will be interpreted as 20xx
2-digit years >= legacy_year will be untreated as 19xx

This key defaults to the value of DefaultCutOffYear.

legacy_year

A boolean value controlling if a 2-digit year is interpreted as being in the current century (unless a base_datetime is set) or if cut_off_year should be used to place the year in either 20xx or 19xx.

This key defaults to the value of DefaultLegacyYear.

clone

Returns a replica of the given object.

Object Methods

base_datetime

Returns a DateTime object if a base_datetime has been set.

set_base_datetime( object => $object )

Accepts a DateTime object that will be used to fill in missing information from incomplete date/time formats.

cut_off_year

Returns a integer representing the cut-off point between interpreting 2-digits years as 19xx or 20xx.

set_cut_off_year( $int )

Accepts a integer representing the cut-off point between interpreting 2-digits years as 19xx or 20xx.

2-digit years < legacy_year will be interpreted as 20xx
2-digit years >= legacy_year will be interpreted as 19xx

legacy_year

Returns a boolean value indicating the 2-digit year handling behavior.

set_legacy_year( $bool )

Accepts a boolean value controlling if a 2-digit year is interpreted as being in the current century (unless a base_datetime is set) or if cut_off_year should be used to place the year in either 20xx or 19xx.

Class Methods

DefaultCutOffYear( $int )

Accepts a integer representing the cut-off point for 2-digit years when calling parse_* as class methods and the default value for cut_off_year when creating objects. If called with no parameters this method will return the default value for cut_off_year.

DefaultLegacyYear( $bool )

Accepts a boolean value controlling the legacy year behavior when calling parse_* as class methods and the default value for legacy_year when creating objects. If called with no parameters this method will return the default value for legacy_year.

Parser(s)

FORMATS

There are 6 string that can match against date only or time only formats. The parse_datetime method will attempt to match these ambiguous strings against date only formats. If you want to match against the time only formats see the parse_time method.

Conventions

Expanded ISO8601

These formats are supported with exactly 6 digits for the year. Support for a variable number of digits will be in a later release.

Precision

If a format doesn't include a year all larger time unit up to and including the year are filled in using the current date/time or [if set] the base_datetime object.

Fractional time

There is no limit on the expressed precision.

Supported via parse_datetime

The supported formats are listed by the section of ISO 8601:2000(E) in which they appear.

Iain 'Spoon' Truskett (SPOON) who wrote DateTime::Format::Builder. That has grown into The Vacuum Energy Powered Swiss Army Katana of date and time parsing. This module was inspired by and conceived in honor of Iain's work.

Tom Phoenix (PHOENIX) and PDX.pm for helping me solve the ISO week conversion bug. Not by fixing the code but motivation me to fix it so I could participate in a game of Zendo.
